NOTE: Heating asphalt may be required for cleaning.
3. Remove the two (2) nuts holding top cover on and

7. Remove the upper end-mount bolts. (Figure 5-34)
8. Slide auger straight out and onto the ground,
placing in the same position. This is important as it
is very easy to install new augers backwards!
9. Check inner auger bearings. Replace if faulty.
(Figure 5-36)
10. Align new augers the same as removed augers,
ensuring they are on correct side to auger material
outward.
11. Reinstall the upper end-mount bolts and torque to
78 ft. lbs. (106 N•m).
12. Feed auger chains back onto the sprocket,
ensuring chains have approximately 1/4” (.635 cm)
of slack. Adjust the auger motors up by tightening
the drive chain tensioners, then tighten the motor
mount bolts,
13. Torque motor mount bolts to 150 ft. lbs. (155 N•m)
and lubricate chains.
14. Reinstall grating.
15. Operate augers to ensure proper function.
NOTE: Auger chains can be lubricated each day by
spraying oil or chain lube through the slots
where auger motor is adjusted.
